RENTON, Wash. (AP) Seattle Seahawks center Justin Britt signed a multiyear contract extension Thursday that will keep the anchor of the offensive line in place beyond the 2017 season.

Coach Pete Carroll said early Thursday that the sides were "really close" to finalizing a deal for Britt and the team announced later in the day that the deal was finished. It's believed to be a three-year deal and takes away any concern that Britt would leave after this season when his rookie contract expires.

"He has been a fantastic leader for us up there," Carroll said. "He had an excellent season and played three spots and started at tackle, guard and center now. We really think he is in the best spot for him. I think it's a recognition and acknowledgement of the player and teammate he has become for us."
